IMPROVEMENT IN DRYlNG-RACKS.

Specification forming part of Letters Patent No. 158,540, dated January5,1875; application filed v June 4, 1874.

To all whom it may concern:

Be it known that I, J AGKSON B. STRATTON, of Waterloo, Seneca county,New York, have invented a machine called a Portable Drying- Itack, forthe drying ol' yeast-cakes, of which the following is a specification:

My invention consists in a portable rack or frame for the holding anddrying of yeastcakes, in such a manner that they will dry rapidly andevenly in a shorter space of time than by any other method in use.

Figure l is a side elevation of my machine. Fig. 2 is the under side ofsame. Fig. 3 is the upper side of same.

A is the frame of the portable rack. It is composed of four strips ofwood or metal, as desired, perforated through the sides along theirentire length with holes marked a a. Said frame A is about one andthree-quarters inch in height, but may be varied in size to accommodatethe size of the cakesto be dried. The upper edges of the ends and sidesare cut or hollowed in for nearly their entire length, in order to leavethe corners higher than the other portions of the frame. The frames canbe made any size. I prefer two (2) feet by six, (6.) The strips marked Bare narrow slats fastened tlatwise across the under side or bottom oftheframe A, so as to leave a narrow space or opening between the edges ofeach slat. These openings or spaces are so arrau ged as to come midwaybetween the cords, slats, or wires D, which extend across the upper andopposite side of the frame A. The wires D are stretched on pegs orscrews. marked C, across the upper side or top of theframe A, as shownin Fig. 3. They extend across from one side to the other, leaving spacesor inter-v Vvals of about onehalf of an inch between each,

.may be used, or strips of wood or metal may be fastened across in thesame relative position, or let into the frame edgewise, so as to leavean open space between their lower edges and the slats B for the freecirculation of air.

v For the purposes of drying, the yeast cakes are set edgewise betweenthe slats, wires, or cords D. The cakes are thicker than the openin gsbetween slats B, which prevent their falling through. By theconstruction of the rack as above described, a free circulation ot' airis insured around each cake from above, below, and through the sides andends, and each cake has almost its entire surface exposed to the actionof' the air, and becomes rapidly, thoroughly', and evenly dry in a shortspace of time.

lhe upper corners ofthe frames being higher than the sides, the framesmay be piled one above the other, and the free circulation of air aroundeach cake maintained, so that a permanent rack for holding frames may bedispensed with.

I claim as my invention- The combination of the grating or slats B, andthe cords, wires, or slats D, with the perforated frame A,Vin the mannerhereinbefore set forth and described. f
